This document provides installation instructions for Bryant Legacy Line single-stage air conditioners. Before starting, ensure you have read the entire manual. Key safety requirements include wearing protective gear, using a fire extinguisher during brazing, and ensuring the main electrical disconnect is in the OFF position before servicing. Never use oxygen for leak testing.
Installation and Mounting
Select a location for the unit away from windows, patios, or decks to minimize noise. The unit must be installed on a solid, level mounting pad. If local codes require, use tie-down bolts through the base pan knockouts. For rooftop applications, mount on a level platform above a load-bearing wall and isolate the unit from the structure to minimize vibration.
Clearance Requirements
- Service end: 24 inches (609.6 mm)
- Above unit: 48 inches (1219.2 mm)
- One side: 6 inches (152.4 mm)
- Remaining sides: 12 inches (304.8 mm)
- Between units: 24 inches (609.6 mm) or 18 inches (457.2 mm) if no overhang within 12 feet.
Refrigerant Piping and Connections
Use refrigerant-grade tubing. Keep lines as direct as possible and avoid contact with water pipes, ductwork, or wall studs. Seal wall penetrations with RTV or pliable caulk. A factory-supplied liquid-line filter drier must be installed in the liquid line. After connecting, the system must be evacuated to 500 microns to remove moisture and contamination.
Electrical Connections
Ensure field wiring complies with local and national electrical codes. Use copper wire only. The disconnect switch must be within sight of the unit. Route 24V control wires through the grommet and connect to the thermostat. For 3-phase units, a monitor is factory-installed; if the LED flashes, interchange two field-wiring leads on the contactor.
System Charging Procedures
The unit must operate for at least 15 minutes before checking the charge. Favorable conditions for charging are outdoor temperatures between 70°F and 100°F (21°C - 38°C) and indoor temperatures between 70°F and 80°F (21°C - 27°C).
Charging Methods
- Units with TXV: Use the subcooling method. Refer to the rating plate for required subcooling temperature.
- Units with Indoor Piston: Use the superheat method. Refer to the provided superheat charging tables based on outdoor temperature and indoor wet-bulb temperature.
Start-Up and Maintenance
After installation, perform a final check: ensure wiring is routed away from sharp edges, service valve caps are tightened to 1/12-turn past finger tight, and all panels are secure. Periodic maintenance is required for continued performance; refer to the Owner's Manual for specific schedules.
Practical help
Common problems
Noise in living area
Ensure the unit is located away from windows/decks and that refrigerant tubing does not contact water pipes, ductwork, or wall studs.
3-Phase monitor LED flashing
Indicates a reversed phase. Disconnect power and interchange two field-wiring leads on the unit contactor.
System not cooling properly
Check refrigerant charge using the subcooling or superheat method after the unit has operated for at least 15 minutes.
Before use
- Verify unit is level on a solid mounting pad.
- Ensure refrigerant tubing is not in direct contact with structure components.
- Install the factory-supplied liquid-line filter drier.
- Evacuate the system to 500 microns.
- Confirm electrical disconnect is within sight of the unit.
- Check that service valve caps are tightened.
